MARCELINQ LUQUE NESTAL, OF NEW YORK, N. Y.

REFEIGERATING MACHINE.

Application and December 11, 1924. Serial No. 755,267.

To all whom it may concern:

Be it known that, I, MARCELINO LUQUE NEsrAL, a subject of the King of Spain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Refrigerating Machines, of which the following is a specification.

This invention is directed to an improvement in refrigerating machines, wherein the material to be cooled or frozen is subjected to a reduction of pressure and to an increase vaporization incident to absorbing the moisture from above the treated liquid.

The invention includes a vacuum pump or like pressure reducer, which is connected Y elevation,

. adap ed particularly with the treated liquid container to reduce the pressure on such liquid. an intermediate container being provided for the reception of a substance having an afinity for moisture, so as to absorb the moisture drawn from the surface of the treated lipuid, to thereby increase the vaporization 0 such treated liquid and thus yield its contained heat more quickly.

The invention is illustrated in the accompanyingdrawing, in which Flg. 1 is a view in section, partly in of the improved refrigerating machine.

The improved refrigerating inachine, while designed particularly for making ice cream, is also adapted for cooling water, and is equally effective in cooling bottle goods in their original packages.

formations of the containers to be .a pump cylinder 4. A hollow piston 5 operates in the cylinder 4, thebottom'wall of the piston being formed opening 6, normally closed by an upwardlyopening valve 7. A hollow valve stem 8 is connected with the upper wall of the piston, and communicates withthe interior of the hollow iston, the hollow stem opening at 9 to tie casing beyond the pump cylinder. Secured to the pump cylinder 4: is an auxiliary cylinder 10, a port 11 establishing communication betweenv the cylinders. The upper end of the auxiliarycylinder is threaded to receive the threaded lower end of a pipe connection-12,, and threaded within the lower end of the pipe connection is a nipple 13, having an interior valve seat 14, below which the wall of the nipple is formed A valve 16 for the seat 14 is arranged on the upper end'of a stem '17, guided through the lower end of the nipple and terminally provided with an enlarged pressure disk 18. Obviously on upward stroke of the piston air is drawn through the pipe connection 12, past the valve seat 14, the valve having dropped past the openings, 15, out the outlets 15, through the port 11 and into the pump cylinder. Then on the downward strokejof the piston, the air accumulated in the pump cylinder is forced past the valve 6 and out through the hollow stem 8. In this downward movement of the piston, the valve 16 is forced to its seat 1 1 y the pressure on the disk 18, thus sealing the pipe ponnection, 12 against back pressure.

A container 19 is arranged in the receptacle 1 for a limited vibratory movement,

with an inlet with outlets 15.

tubes andcontainer extensions aregorefeis ably rubber sleeves 28 to assist in maintains ins. a tight connection without; regard to internal pressure; o

A power shift 29 is mount d in the upper yond the ease with a flywheel disk having a handle 30. whe eby rabid movement may be impariedto theshaftj. The innerend "of the shaft is provided with a, disk. 3.1; with a crank connection32 tothe hoiiow piston stem 8. Immediately beyond the i pumpcasingii. the shaft isorovided with an eccentric 33. fihestrap of which isconncoted i of a contained h-qnid wnieruor the xihc. In the use of the machine forrnaking lCQ by a rod34 with the angle lever 23.

Means are provided for admitting and oil to theinterior of the pump cylinder;

to maintain an effective sealing of thepiston,

sndsecn're proper lubrication of the parts A casing 35 is mounted on top of the pump cylinder, and has ,a valved passage 36, open ing into the pump cylinder Within the limits of movement. of the piston. The oil casing 35 is open to the casing 3 above the pump cylinder, throughlopeninns 37, and a rod 33 extends through the oiicasingv and has a. valve 39 for closing the passage 36.- A win 40 arranged within fhe oil casing ends to keep the valve in closed position, :1 cam 41 on the power shaft 29. operating 'ot each half. revoluiion of such shafi to raise a rino: secured on rod 38. tends to raise the valve 39 at eachvhalf stroke of the pump piston to admit oil and air to he interior of the pump cylinder. The piston stem opening in fhe upper end of the pump c'ylinderis larger than the stern. asst 42.? Land .a disk :washer 43. held down by is spring 44 Y encircling the piston stern and hearing atits upper end against a washer engaging he the lower end of the upner'zuide &5 for the. step. At each uo strohe of the piston the disc washer 43 is foreed from ihs sent. and the excess oil is returned to the casing 3 shows the pump cylinder.

The body of vepor iminediately above such material is more rapidly drown oil with the-sir by the use of the moisture absorbent material in the oonminer w, as 1 by the use of such the moisture is absorbed from the air withdrawn by the vacuum pump, and the moisture above fheirested material is more rapidly wifihdrswn, and thus the latent heat of the material dissipated." r f Obviously water may be cooked or frozen ice cream or other food stuifsfbroughtto a state of being con ealed, or bottle cont-ainedli uids reduce rapid a simple manner, all that isjrequired is the introduction of a Isufiicient quantity of in temperature in s sulphuric acid or the like in the container 19.. and the operation of the power sheik.

The temperature reduction is obviousiy secured in a more rapzd manner as a result material end acid containers. The treated material 15 thus more readily open to ores sure reduction, and the agitation: of then ois tore absorbent increases its capacity for i cream n example, a sgiecisly y e 023cm- ;tamer is preferred This conhnner iilns or trntcd particularly in E g. if; comprises a,

In the use of the device for oooiing bottle I goods in their original packages, the coniznincr comprises s body portionr of conxcal form with dfiwldened mouth, and a neck portion adapted for sealing engagement at 51 with the body portion. ihe neck portion has an upstanding hollow projection to accommodate the length of the botties placed therein, and is formccl ni" one side with an openingfiilfior the. connection there i ;o. of the tubsles. The hoitles in be cooled, ndicated at 5f'aneg'placed in' this container *imd water is placed in the-body 49 surrounding the bottle.

An important feaeure of the irzveniion is the mouintingbf the entire apparatus in the c case-like receptacle 1 to provide for com veniencstorage and transporetion.
